cds-question@unistra.frx-ray-sourcesultraviolet-sourcesDuring 1990-1991 the Wide Field Camera (WFC) on the ROSAT satellite performed the first all-sky survey at EUV wavelengths. The survey was conducted in two 'colours' using broad-band filters to define wavebands covering the ranges 60-140A and 112-200A. It was fully imaging, with effective spatial resolution of about 3arcmin FWHM, and point source location accuracy of typically better than 1 arcmin. From an initial analysis, Pounds et al. published the WFC Bright Source Catalogue (BSC) of 383 sources. In this paper we report results from reprocessing of the complete survey database; the resulting list of sources is the '2RE' Catalogue. It contains 479 sources, of which 387 are detected in both survey wavebands, a significant advance on the BSC (80 per cent versus 60 per cent). Improvements over the original BSC include: (i) better rejection of poor aspect periods, and smaller random errors in the aspect reconstruction; (ii) improved background screening; (iii) improved methods for source detection; (iv) inclusion of a time-variability test for each source; (v) more extensive investigation of the survey sensitivity. We define the catalogue selection criteria, and present the catalogue contents in terms of tables and sky maps. We also discuss the sky coverage, source number-flux relations, optical identifications and source variability.1995MNRAS.274.1165Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/274/1165CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://ledas-ftp.star.le.ac.uk/rosat/2re/cat : the original fileJ/MNRAS/260/77 : the ROSAT-WFC Bright Source Catalogue (Pounds et al. 1993)J/A+AS/114/465 : the ROSAT XUV Pointed Phase Source CatalogII/203 : Second Extreme Ultra-Violet Explorer Catalog (1996)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges et al. 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/274/1165https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/274/1165http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/274/1165https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/274/1165https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/274/1165http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/274/1165GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/274/1165/catalog (The 2RE catalogue, Table 2 of paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/274/1165/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/274/1165/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/274/1165/catalog?GETtext/xml+votable180.050000true0.97987543.59477780.005555555555555556ROSAT6/90 311 447 493 538 674 845 861 924 1058 1077 1185 1283 1412 1504 1603 1704 1762 1875 1890 2076 2549 2574 2585 2597 2734 3109 3204 3210 3343 3566 3610 3693-3694 3768 3922 3986 4143 4158 4190 4444 4468 4566 4591 4736 4808 5025 5176 5321 5367 5377 5423 5450 5491 5558 5569 5578 5772 5804 5871 5893 5898 5902 5936 5941 6036 6040 6045 6047 6070 6122 6160 6169 6241 6274 6340 6384 6410 6879 6944 7212 7220 7561 7610 7631 7763 8145 8155 8534 8790 9194 9433 9442 9512 9614 9651 9808 9962 9974 10130 10156 10194 10203 10225 10246 10386 10481 10519 10605 10771 10969 11112 11222 11225 11290 11339 11391 11400 11403 11486 11514 11534 11612 11620-11621 11636 11673 11690 11764 11856 11973 12031 12088 12092 12111 12228 12533 12698 12908 13024 13110 13133 13250 13301 13308 13440 13451 13512 13670 13743 13778 13802 13947 13966 14005 14018 14208 14263 14281 14402 14476 14512 14654 14667 14888 15169 15243 15267 15287 15351 15355-15356 15391 15674 15861 15914 16046 16052 16158 16186 16220 16338 16614 16707 16834 16857 16886 17058 17415 17736 17790 17965 17989 18007 18234 18549 18889 19261 19541 19543 19670 19930 19970 20071 20263 20286 20327 20423 20492 20494 20507 20602 20701 20710 20760 20915 20922 20940 21050 21060 21069 21082 21094 21118 21199 21241 21285 21386 21416 21501 21736 21763 21885 22051 22066 22069 22100 22120 22146 22148 22289 22300 22459 22491 22513 22616 22707 22709 22749 22773 22846 22856-22857 22870 22904 22939 23101 23137 23140 23191 23230 23272 23369 23385 23533 23538 23545 23564 23644 23678 23719 23731 23789 23960 23964 24151 24160 24239 25138 25585 25659 25793 25869 25930 26064 26174 26460 26509 26521 26555 26668 26678 26851 26911 26924 27322 27462 27833 27855 27872 28026 28041 28126 28129 28149 28151-28152 28243 28252 28259 28384 28389 28481 28561 28982 30167 30406 30626 30753 30833 31666 32106 32147 32211 32257 32516 32575 32617 32743 32781 32836 32878 33067 33116 33287 33306 33313 33378 33576 33582 33639 33691 33694 33814 33849 33861 33930 33937 34074 34097 34163 34191 34197 34244 34266 34280 34286 34398 34464 34652 34676 34680 34822 35080 35093 35150 35191 35354 35573 35626 35690 35796 35948 36234 36526 36697 36739 36836 37041 37096 37196 37419 37427 37746 37808 37825 37900 38095 38222 38324 38430 38804 38913 38936 38950 39192 39245 39284 39354 39383 39464 39523 39612 39689 39825 39829 39853 39880 39954 40131 40321 40356 40408 40466 40640 40656 40784 40904 40944 41283 41295 41465 41549 41591 41679 41763 41769 41798 41981 42216 42420 42454 42601 42701 42751 42760 43623 43699 43850 43947 44176 44361 45154 45380 45382 45419 45580 45782 45815 45909 45962 46180 46281 46385 46598 46612 46700 46922 47002 47011 47014 47180 47459 47496 47598 48115 48163 48263 48274 48516 48572 48589 48905 48941 49112https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/274/1165?format=asciiX-rayEUVdefaultJ/MNRAS/274/1165/catalogThe 2RE catalogue, Table 2 of paperrecnoRecord number assigned by the VizieR team.
